A company called Mootral has created an all-natural feed supplement that, when given to cows, can reduce their methane gas emissions by 30 percent.

“On a global scale, livestock accounts for 15 percent of the greenhouse gas emissions. At the same time, consumers want and need meat and milk products, Mootral CEO Christoph Staeuble said in a statement. “Cows are a crucial factor in our environmental ecosystem and the economy, since they transform biomass, such as grass, into essential nutrients for a growing population.
